Be it known that I, OnvrLLi; MARLY, of Garrettsrille, in the county ofPortage, and State of Ohio, have invented a new and improved Roofing;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification. p

This invention relates to a new and improved method of constructing theroofs of buildings, whereby the same are more durable and moreeconomically made.

It consists of tiles saturated with raw coal-tar,'madc inthe same way asordinary brick, havingall the edges bevelled, being thicker at one end,and laid upon the roof with the thinner end towards the eaves, and thespaces between the tiles, formed by the bcvelled sides ofthe same, llcdwith a cement made of raw coal-tar andelay. In the accompanying plate ofdrawings- Figure 1 represents a plan view of a root" with the tileslaid.

Figure 2 represents a longitudinal section of the same, taken in theline x fig. 1, showing the spaces made by the bevelled sides of thetiles. i

Figure 3 is a crosssection ot' the same, taken in the lineg/ y, iig. 1,showing the spaces made by the bevelled ends of the tiles. y

Figure 4'is aplan view of one of the lower row ot' tiles, forming thetrough.

Figure 5 represents a longitudinal section of the same.

Similar letters of reference indicate corresponding parts.

The roof A is made iu the usual way, of boards laid closely together,either covered with felting or not.. The tiles a are made otanyconvenient size, of the same material and in the same way as commonbricks, hav-` ing all their edges bevelled, as shown in the drawing,fig. 4, and are made thicker at one end than' the other, so as to leavea projection or elevation, as represented at c, fig. 5. The sides andends.are bevelled, so that the tiles a are broader and longer on thelower or under side, so that when laid together the spaces S are leftbetween said tiles a to receive the cement. The tiles a are saturatedwith raw coal-tar, `which they readily absorb, so that said tiles a arerendered completely impervious to water. Said tile-s a are made thickeratene end, so as to leave an elevated projection, which on au inclinedorslanting roof prevents the cement, when warm, from running down to theeaves. Said tiles a are laid upon the boards or felting of the roof,with'the thinner end towards the eaves, as represented in the drawing,fig. 3, in the same way as bricks are laid in building, so that thejoints are broken, as represented in the drawing, fig. 1. p

The tiles 6, ot" which the lower row'oi' tiles is made, are formed by aange on the lower end, at right angles to the body'ot` the tile, thespace between the flange and the body of the tile beingr partly filled,so as, when they are laid together, said tiles form a spout or trough,as represented in the drawing, figs. 3, 4, and 5. Said tiles b have twoor more ot their sides bevelled, in the same manner as thc tiles a.Said' tiles b are used along the sides ot' the root` and along theedge,where they constitute an caves-trough, as shown in the drawing, withinand not projecting beyond the roof. Said tiles b are made of the samematerial, in the same way, and are in like manner saturated withcoal-tar, as the tiles a. The cement with which the spaces S are filledis made of pulvcrized blueclay and raw coal-tar, in about the proportionof eighty or one hundred pounds of the clay to f four gallons ofcoal-tar, or in such proportions of the said materials asV shall makethe mass of proper consistl ency to be easily worked, and may be usedfor filling up spaces between the tiles, or generally for making roofseither water or fire-proof.

The saturated tiles a and the saturated tiles b, having the spaces Sbetween them laid and filled with the dement, as above described,constitute a cheap water and fire-proof root', free from the objectionsto the cement and tile-roofs for buildings now commonly in use.

I claim as new, and desire to secure by Letters Patent- 1. A roof,composed of tiles a and b, having spaces S between them for awater-tight cement, substantially as shown and described, and for thepurposes set forth.

2. '.lhe saturated tiles a and the saturated tiles I, substantially asshown and described, and for the purposes set forth.

3. The lower or outer row ot' tiles b, when laid together, forming ancaves-trough, substantially as shown and described, and for the purposeset forth. p

The above specification of my invention signed by me, this 30th day ofSeptember, 1867.
